Upper School Admissions

Ready to take the next step? Let us assist you throughout the application process.

Thornton Academy serves day students from over 20 different towns in Southern Maine and New Hampshire and boarding students from the US and over 50 countries around the world. We offer rolling admission throughout the year, meaning that if we have space, we are happy to consider your application as soon as your application file is complete. The application process is simple, and our team is here to help you every step of the way. 

A long-standing town-tuitioning program providing area students with educational choice continues to allow Thornton Academy to enroll the majority of students from the towns of Saco, Dayton, and Arundel while maintaining its own independence. If you are a resident of these towns, contact our registrars.

We are currently accepting students for the 2024-25 academic year on a rolling basis. Applications for 2025-25 are also open.

Step-by-step admissions process

Thornton Academy has been very good for both of our kids.  The teachers never fail to impress me with their dedication to their students, preparedness for the class, compassion for all learners and just their wonderful spirits.
